BALANCED wmnow.

Application filed May 24, 1912, seriai m. 99,414. Renewed July 21, 1920.Serial No. 398,396.:

To all whom it may concern Be it known that I, WALDO S. KELLOGG, acitizen of the United States, residingat New York city, in the countyand State of'New York, have invented certain new and useful Improvementsin Balanced Windows, of which the following is a full, clear, and exactdescription. 1

My invention relates to so-called balanced windows of the t pe describedin United States Patent to G. Abell', No. 788182, granted April 25th,1905, reissued Novemher 14th, 1905, No. 12 108, and Letters Patent No.821510 to Alexander Knox, granted May 22nd, 1906, in which theupper andlower sashes are pivotally connected with the frame in such manner asto'permit substantially vertical movement-of the sashes and permitting alimited swinging or'turning movement of each on its pivotal connection IThe chief object of my present invention is to provide a construction inwhich the re versal of the window can be obtained for cleaning and atthe same time eliminate the guide pins and the various guide pin slotsin the window frame as shown in the Knox patent. At the same time a muchsimpler construction is obtained which has the advantage of showing onlya, plain frame instead of one out up with a multitude of slots. Thisadvantage is of special importance when a metal frame, metal covered orsocalled kalamine frameis employed. Here any increase in the number ofslots greatly increases the cost of the window. Another feature of mynew window is that when cleaning the window, an outward reversal of theupper sash is absolutely prevented. This does away with the dangerofthe'window falling out, breaking the glass and causing possible injuryto pedestrians below.

The invention which consists in the novel features of construction,arrangements of parts, and combinations of elements hereinafterdescribed and more particularly set forth in the claims, will be moreclearly understood when described in connection with the accompanyingdrawings, wherein- Figure 1 isa central vertical section show ing thesashes opened. The sashes are also indicated in closed position by thedotted lines. 7

Fig. 2 is a central sectional view of Fig. 3. Fig. 3 shows an outsideelevation of the 'window,'the upper sash being turned at rightanglespreparatory to reversing for cleaning.

Figs. 4 5 and" 6 guide hook.

are details of the sash Specification of Letters Fatent; Pat ted s tpi20 i Fig. 7 is a modification of the sash guide hook preferably usedonthe lower sash.

In Fig. 1, 10 and 11 are the upper and lower sashes respectively. Theyare connected together by the balance arm 12. The i 7 ends of thebalance arm are connected to the sashes by the pivotal connections 13andli. 15 is the jamb of the window. On the jamb at 16 is shown thepivot connecting the balance arms to the frame. The j'amb' 15 is shownin a sectional viewin is shown a rabbetedjamb with a longitudinal groove19. The groove is designed to receive the parting strip 20. The face ofthe jamb inside the groove 19 for the parting Fig. 5. Here strip is setback slightly from. the face of the jamb outside the groove 19. f Thisis shown at 17 "and 18in which 17 shows the plane of the 'jamb insidethe groove and strip, and 18 the planeoutside. -The parting v strip 20is shown in sections 20,20 and 20". 20 and20 may be removable. l s

By referringto Figs. 1' and '3 it will be seen that the groove and thegeneral contour of the jambs are similar and continuous throughout theirlengths" There are no grooves or slots which terminate part way; Norare'th'ere any slots'running across the jamb; all run from end to end;This is of decided advantage in manufacturing, as the forming of a metalframe is a simple matter where the grooves are continuous throughout.It, should also be noticed that no slots are visible at anytime, whenthe window is in either open-or closedposition.

In place of the studsrunning ingrooves,

as shown in the Knox and Abellpatents,1

provide sash guide hooks 21 attached'to the and the" web 2 1. The flange22 is flat and has holes drilled init to receive the supportingscrew's25. The web portion of the hook is ofa height substantially equalto the width of the parting strip. Thefiange 23 is not in an exactlyparallel P13116110 the flange 22 but'at a slight angle to it. It is alsoslightly curved as shown at 26. The object of thislower sash. The flange22 is screwed to' the sash by the support screws in such a position thatthe web of the hook will come in close proximity to the parting stripand the flange 23 will project over the parting strip.

See Figs. 1, 3 and 5. The flange23 is of such length and the hook is soplaced on the sash that the tip 27 of the flange 23 extends close enoughto the jamb to engage the jamb 18 when .a section of the parting stripis removed. Thisprevents the Window from falling outward.

"The upper sash is reversed for cleaning by removing the part 20 of theparting strip. This allows the sash guide hooks and the sash itself topass through the parting strip and into the room where the cleaning canbe carried out. When the sash is in this inward position the outside ofthe window is inward so that it can be easily cleaned.

The window is then returned to normal po-' sition and the insidecleaned.

-The lower window is reversed in much the same way. A portion 20 of theparting strip can be removed and the hook retracted therethrough. Or ifdesired, the hookcan be made with a spring connection so that it can'bepulled inward and freed from the parting strip.

A detail view of the spring hook is shown in a preferred form in Fig. 7.Here the parts 27, 23 and 24 are the same general form asthe other hook.The fiat part 29 is in this case not attached to'the window but isslidably mounted in a piece 81, which is attached to the sash. The endof 29 is bent up and around as shown in 30. This part 30 serves as afinger hook. A resilient c011- nection 32 is provided. This is fastenedto the hook and cooperates with the plate 31 to force the hook to theleft. VVhen'it is desired to reverse the window for cleaning the windowis first sli htly raised; The cleaner reaches out under the sash andgrasping the hooks at 30 retracts them inwardly until the tip 27 of thehook clears the parting strip. The window can then be swung inward andreversed. V

The reason for the sllght curvature 26 on the guide hooks is that as thewindow is lowered the sash tilts away from the parting strip and theguide hook is rocked. The curvature 26 on the hook allows for thisrocking and at the same time keeps the guide hook in contact with theparting strip.

It is to be understood that many departures may be made from the above,which will be apparent to those skilled in the art. The guide hooks maybe applied to Windows of a different type from the one described, forexample, in windows wherein the sashes lie in one plane when in closedposition.

I claim 1. In a window of the kind described, the combination of upperand lower sashes, a. frame therefor, removable parting strips in saidframe, a balancing lever pivoted to the frame and having its endspivotally connected to the upper and lower sashes, means cooperatingwith the parting strips to guide the sashes on. a movement thereof, saidparting strips adapted to be removed to reverse the windows forcleaning, said means on one of said sashes adapted to contact with theoutside jamb of the frame to prevent the window fromreversing outwardly.
